John Theriault, Apple's head of security, has left the company on early retirement, possibly as a result of how the case of a lost iPhone 4S prototype was handled this summer, according to a new report.

Hackers have succeeded in bringing a limited port of Apple's new Siri voice assistant feature onto "jailbroken" versions of the iPhone 4 and the fourth-generation iPod touch, though they have noted that the workaround is not ready for a public release.

Though the new Samsung Galaxy Nexus sports a 720p HD display, its 4.65-inch screen is said to be held back by cheaper technology that gives it a lower pixel density and poorer color accuracy than Apple's Retina Display found on the iPhone 4S and iPhone 4.

Verizon, the largest wireless carrier in the U.S., sold two million iPhone 4 units last quarter, falling 700,000 short of rival AT&T. The carrier also declined to reveal its launch numbers for the iPhone 4S.

There was not enough evidence to indict Gizmodo editors in last year's iPhone 4 prototype debacle, though actions and correspondence by the site's editors were called "juvenile" by the court case's prosecuting district attorney.

Just 24 hours after opening up pre-orders for the new iPhone 4S, Apple has rolled back expected shipping times for the device from expected delivery on the Oct. 14 launch date to an estimate of 1-2 weeks.
